What does the rain on your head say?

Down on the head, from the folk "down on the head, sun on the tail" and "down on the head, down on the head".

Shower the head first, dry the tail.

Shower head means that it is raining when it falls, and sunset tail means that when it ends, the weather will be mainly sunny, because the sun will be fine, so it is the sunset tail. Literally, this proverb means that if it rains during lodging, the rainfall in the dog days will mainly concentrate on the first and second lodging, and at the last lodging, the rainfall will decrease, and even drought may occur.

For farmers, the first lodging and intermediate lodging are the most vigorous seasons for crop growth. At this time, the demand of crops for water is large, and if it rains during lodging, it will be beneficial to crop growth. By the end of lodging, the crops have entered the final pollination and filling stage, at which time the demand for water of crops began to decrease. If there is too much rain, it will affect the pollination and filling of crops, so it is good for farmers to rain on the day of lodging.

Second, there is rain on the head, and there is rain on the head.

Literally, this proverb means that if it rains on the head, the middle and the end will be rich. If it doesn't rain for the first lodging, it will be mainly sunny and seldom rain during the middle lodging and the last lodging.

In the past, there was no technology and equipment to predict the future weather. People can only sum up the changing rules of the weather from years of life and work experience. Dog days are the season with the most rainfall in summer. If there is plenty of rain at the beginning, it means that there will be a lot of rain this summer, so there will be a lot of precipitation in the middle and late stages. But when the weather is mainly sunny at the beginning, it means that it is a dry year, so there will be little precipitation not only at the beginning, but also at the middle and end.

After three days and three rains, the grain will be put into storage.

There are three rains in three days, not specifically three rains, but if there is rain in the first, middle and last three days, then farmers will have a very good harvest no matter what crops they plant.

After entering the dog days, due to the high temperature, the water in the soil evaporates greatly, and the soil in the farmland is often dry for three days and five days, so the demand for rainwater by crops in the dog days is particularly large. A good harvest of crops planted in summer has a lot to do with the rainfall in dog days. If there is enough rainfall in dog days, the harvest achievement of crops is guaranteed. If the rainfall is less, the crop yield will be reduced, and if it is serious, the grain will be completely harvested. That's why there is a saying that "it rains three times in the dog days, and food enters the warehouse".

Fourth, the king is soaked, one day.

Wang Fu refers to the first day of lodging, so if this proverb is taken literally, it means that if it rains on the day of lodging, the whole dog days will be full of precipitation. The ancients used "one rain a day" to describe the rainfall in dog days. Although there will actually be some gaps, there will generally be light rain for three days and light rain for five days.

Although the rain in rainy days will make the crops in the field grow sturdily, at the same time, too much heavy rainfall will also cause the crops in the farmland to be damaged. Therefore, in dog days, people should not only prevent the dryness caused by the hot weather, but also prevent too much rainfall, which will lead to moldy crops in farmland.
